Set name: 100Ah Bluetooth (Group 24)
As a full-time RVer here in sunny (and sometimes stormy) Florida, I finally ditched my old lead-acid batteries for the LiTime 12V 100Ah Group 24 Bluetooth LiFePO4 Battery, and wow—what a game-changer! This compact powerhouse fits perfectly in my standard Group 24 battery box as a drop-in replacement, but it delivers way more performance than anything I've had before. Right out of the box, the build quality stands out: lightweight at around 23-25 lbs (about 2/3 lighter than my old AGM), yet it packs a full 1280Wh of usable energy with 100% depth of discharge—no more worrying about killing the battery by running it too low. The 100A BMS handles heavy loads effortlessly (up to 1280W continuous, with a massive 500A peak for 1 second), so my fridge, lights, fans, and even a small inverter run smoothly without hiccups. The Bluetooth 5.0 feature is my favorite part—pairing with the LiTime app is quick, and I can monitor voltage, current, SOC, temperature, and more in real-time from my phone. No more guessing how much juice I have left! Installation was plug-and-play: connected in parallel with another for extra capacity, charged it up with my LiFePO4-compatible charger, and it's been rock-solid. It handles hot Florida days without issue (IP65 waterproof rating helps), and the EV-grade cells promise 4000+ cycles at 100% DOD—meaning this should last me 10+ years easily. Compared to lead-acid, it's night and day: faster charging, more runtime, zero maintenance, and no sulfation worries. For the price, this LiTime battery outperforms many pricier brands I've tried. Perfect for RVs, solar setups, trolling motors, or off-grid adventures. If you're ready to go lithium and want smart monitoring in a compact Group 24 size, grab this one—you'll wonder why you waited so long! Highly recommended.

Set name: 230Ah RV Battery(APP)
This is a powerhouse battery. Been using it a year in my travel trailer, and I’m charging it up for the beginning of the season as I write this. Never had an issue with the battery itself. The app can be a touch finicky here and there but overall, it’s good for monitoring and just turning the discharge on and off. I track most everything through my Victron app. Great battery at a great price. Watch LiTime’s website for sales.

Set name: 100Ah Bluetooth (Group 24)
Bottom line up front: This battery is pretty awesome on it's own; it's amazing for the price. Update: As of 6/10/25 this battery is still trucking along without any issues. It's lived in the bed of my truck through the heat of summer and the cold of winter without fail. The BMS shows 18 cycles in 10 months with frequent use. The IOS app is still a little glitchy. If you fail to disconnect from the battery in the app and walk away, when you attempt to reconnect again it doesn't show current status of the battery without disconnecting in the app and killing the app. First, LiTime's packaging is on point. The battery showed up in a heavy duty box well protected by foam. Even the package smashers couldn't damage it. I'm using this to power an ARB Classic fridge and a Puma PD1006 compressor in my truck. It works great in this application when paired with a quality DC to DC charger and solar controller. I'm using it with a Redarc BCDC1225 so the alternator and solar charging are all in one, which is nice. The Puma PD1006 compressor draws 30 amps when running; battery handles it like a champ. The Bluetooth is functionality is great. The range on the Bluetooth is much better than most other Bluetooth devices. I can be 50+ feet away with the battery in a covered truck bed and check the status. The app is just "okay". It seems to work flawlessly when monitoring the battery when it's not being charged, where it gets glitchy is when monitoring it while charging. The app will not update the battery status after a while, requiring you to disconnect from the battery and reconnect. Then it works. Outside of that, it works good at monitoring the power going in and out of the battery. The app gives a rather annoying notification whenever you lose connection due to going out of Bluetooth range. If LiTime fixes the battery status update issue, the app would be solid. Overall, recommend this battery if you're looking for a quality LFP battery at an affordable price.

Cannot control charge current so it’s overwhelming my trailers charger at over 50 amps. Battery came dead. Now I have to buy another charger. Shame shame shame and another $100… UPDATE: My “auto-detect” inverter/controller panel in my trailer appears to be struggling with “auto-detecting” the proper battery type. The battery itself is awesome and works great. Just be prepared that your RV will need more than just a lithium battery if you choose to go down that road. Most likely will need some tweaking or upgrading of the charging for said battery.

Set name: 100Ah Bluetooth (Group 24)
This packs 1.28 kWh of power which is quite good, and it doesn't weigh too much either, ~20 lbs. Beware tho that they shut the BMS off for delivery, so many chargers will not recognize it. It showed up reading only 2.8 V and my charger would not recognize it. You must have a charger that will go from 0V OR, like me, I had to jump start it. I had to get some voltage on it for the charger to recognize it was a battery. I did it with a male cigarette 12V connector to bare wire connected to the battery, which put 13+V on the battery. Then, it charged right up. It could be done with regular jumper cables with your car battery too. Or, as mentioned above, it can be charged with an expensive charger that will charge from 0V. Now that it's fully charged, however, I should not need to jump it, unless the voltage runs way low again.
